There's a Bridge in Scotland that's famous for Dog Suicides:


Overtoun Bridge has gained media attention for the number of dogs that jump off it's side to their death. Studies show that since the 1950s and 60s at least one dog per month has jumped off of the bridge. Dogs that jump, fall 50 feet into waterfalls below the bridge. Most die, though a few have survived. When they were taken back to the bridge, they jumped off of it again!


Some consistency has been found in the phenomenon. For instance, the dogs that jump tend to have long snouts and jump from the same side of the bridge on clear days. An expert was brought in to investigate the phenomenon after the bridge received so much media attention. After examining sight, smell, and sound factors, the expert zeroed in on scent. He discovered that mice and mink were found in the undergrowth on the side of the bridge the dogs were jumping from. After experimenting he suggested that the potent odor from male mink urine was drawing the dogs to the bridge and their ultimate death.
